Description

Technical Field

[0001] This invention relates to the field of motor track technology, and in particular to a tracked, rapidly deployable motor track. Background Technology

[0002] A linear motor is a power device that directly converts electrical energy into linear motion mechanical energy. Because it eliminates the need for intermediate transmission mechanisms and boasts high transmission efficiency, linear motors have been widely used in industrial fields such as rail transportation, industrial control, and CNC machine tools.

[0003] As linear motors are used in more and more fields, the demand for ultra-long linear motors is increasing due to the growing use of high-speed and long-stroke applications. However, ultra-long motors are difficult to transport.

[0004] In existing technologies, multiple short linear motors are typically spliced ​​together to achieve higher linear motion speeds. However, connecting multiple linear motors requires pre-setting motor tracks for operation to ensure accurate connection. These tracks need to be pre-set, requiring tooling installation in industrial plants and pre-setting trenches or welding anchor bolts on outdoor surfaces. This process is time-consuming and labor-intensive, making it unsuitable for time-sensitive applications requiring rapid operation.

[0005] Furthermore, the transfer of linear motors is generally carried out using a crane, which requires considerable preparation and external conditions including a crane, operators, and a supervisor. There are also certain safety hazards during the lifting process. If on-site equipment is insufficient, the transfer of linear motors will be difficult.

[0006] After the linear motor is connected, the power cabinet and the linear motor are connected by a cable. For long-distance cable connections, the cable is heavy and difficult to drag. Long-distance connections are time-consuming and laborious. In addition, the cables are messy during the connection process, making operation inconvenient and posing safety hazards.

[0007] Currently, the commonly used linear motor track laying, linear motor transfer, and cable laying are three separate systems that are completed sequentially. This process is labor-intensive, inefficient, and cannot meet the needs of time-sensitive and rapid operations. Summary of the Invention

[0008] Based on the above analysis, the present invention aims to provide a tracked, rapidly deployable motor track to solve the problems of cumbersome, time-consuming, and labor-intensive linear motor track laying operations and difficulties in transporting linear motors in the prior art.

[0009] The objective of this invention is mainly achieved through the following technical solutions:

[0010] A tracked, rapidly deployable motor track includes a drive assembly and a track. The drive assembly drives the track so that the track can be rolled up or unrolled to lay or retract the motor track.

[0011] Furthermore, the track includes an inner track and an outer track; the outer track can be stacked on the outer wall of the inner track, and the drive assembly is used to drive the outer track so that it can unfold or stack on the outer wall of the inner track.

[0012] Furthermore, the drive assembly includes a rotary motor, a drive sprocket, and a tensioner; the rotary motor is disposed inside the drive sprocket and is used to drive the drive sprocket to rotate.

[0013] Furthermore, the inner track is a closed-loop track structure, one end of the outer track is a fixed end, which is fixedly connected to the inner track, and the other end is a free end. The free end can be rolled up or unfolded on the outer wall of the inner track to realize track retraction or laying.

[0014] Furthermore, the drive sprocket and the tension wheel mesh with the inner track, and the drive sprocket and the tension wheel are spaced apart.

[0015] Furthermore, the drive sprocket and the tensioning wheel are arranged parallel to each other in the horizontal direction.

[0016] Furthermore, it also includes a connecting plate; the fixed end of the outer track is connected to the inner track via the connecting plate.

[0017] Furthermore, the outer track includes multiple single-link chains, which are arranged in parallel with each other.

[0018] Furthermore, the single-link chain includes a convex circle and a groove.

[0019] Furthermore, the track includes an outer track, and the drive assembly includes a rotary motor and a drive sprocket; the drive sprocket and the outer track are meshed together, and the rotary motor is used to drive the drive sprocket to rotate, so that the outer track can be rolled up or unrolled around the drive sprocket, thereby realizing the retraction or laying of the motor track.

[0020] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0021] (1) The tracked rapid deployment motor track of the present invention includes a drive assembly and a track. The drive assembly is used to drive the track to deploy or fold up, thereby realizing the laying or folding of the motor track. The tracked rapid deployment motor track provided in this embodiment abandons the traditional multi-segment short linear motor splicing method of motor track, changes the multi-segment linear motor transfer method, and does not require additional pre-setting motor track operation steps. The linear motor track is pre-laid directly by unfolding the outer track, which greatly improves the efficiency and accuracy of track laying, while reducing the expenditure of manpower and material resources. This makes the motor track convenient, fast, and efficient, and also facilitates the transportation and movement of the motor track.

[0022] (2) In this invention, the drive sprocket and tensioning wheel mesh with the inner track, and the distance between the drive sprocket and tensioning wheel is set so that the inner track of the closed-loop structure can be fully stretched and tensioned, thereby forming a track with a fixed shape. This allows the outer track to wrap around the fixed-shape inner track, thus enabling the length of track laying to be calculated by the number of turns of the outer track around the outer wall of the inner track, for the purpose of accurately determining the track laying length.

[0023] (3) The active sprocket and tensioning wheel of the present invention are arranged in parallel in the horizontal direction, so that when the outer track is wrapped and stacked on the inner track, the track space in the vertical direction can be evenly distributed to the horizontal direction, saving the track space in the height direction, which facilitates the overall transportation and storage of the track.

[0024] (4) In order to enable the outer track and the inner track to be fixedly connected, the present invention provides a connecting plate at the fixed end of the outer track and the side end face of the inner track. The connecting plate is sleeved on the pin of the fixed end of the outer track and the inner track, so that the two cannot be displaced relative to each other.

[0025] (5) Each link of the chain in this invention includes a convex circle and a groove. The convex circle is disposed on the upper surface of the link and the groove is disposed on the lower surface of the link. When the track is coiled, the convex circle at the top of the link of the outer track engages with the groove at the bottom of the link of the inner track, so that the stacked tracks can engage with each other and avoid misalignment.

[0026] (6) The inner spacing of the single chain link of the present invention is M, the spacing of the inner edge of the nut is N, and the width of the linear motor is L. Among them, the width L of the linear motor needs to be between the spacing N of the inner edge of the nut and the spacing M of the inner side of the single chain link, that is, it needs to satisfy the following relationship: N < L < M, in order to ensure that the bottom of the linear motor can contact the nut so that the linear motor can be rotated through the nut.

[0027] (7) The single-link chain in this invention also includes a transfer assembly for transferring the linear motor. The through hole on the single-link chain is clearance-fitted with the connecting pin, ensuring that the connecting pin can rotate freely in the through hole of the single-link chain. The linear motor is placed on the nut, and the linear motor and the nut are rolled together to realize the transfer of the linear motor.

[0028] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or may be learned by practicing the invention.

[0041] The following detailed description of a tracked rapid deployment motor track, with reference to specific embodiments, is provided. These embodiments are for comparative and illustrative purposes only, and the present invention is not limited to these embodiments.

[0042] Example 1

[0043] A specific embodiment of the present invention, such as Figures 1-2 As shown, a tracked rapid deployment motor track is disclosed, including a drive assembly, an inner track 3 and an outer track 4. The outer track 4 can be stacked on the outer wall of the inner track 3. The drive assembly is used to drive the outer track 4 so that it can be deployed or stacked on the outer wall of the inner track 3 to realize the laying or folding of the motor track.

[0044] Compared with existing technologies, the tracked rapid deployment motor track provided in this embodiment abandons the traditional multi-segment short linear motor splicing method of motor track, changes the way multi-segment linear motors are transported, and does not require additional operation steps for pre-setting motor tracks. The linear motor track is pre-laid directly by unfolding the free end of the outer track, which greatly improves the efficiency and accuracy of track laying, while reducing the expenditure of manpower and material resources. This makes the laying of motor tracks convenient, fast and efficient, and also facilitates transportation, movement and storage.

[0045] Furthermore, the inner track 3 is a closed-loop track structure, one end of the outer track 4 is a fixed end, which is fixedly connected to the inner track 3, and the other end of the outer track 4 is a free end. The free end can be stacked and rolled outward to the outer wall of the inner track 3 to retract the track, or the free end can be unfolded from the inner track to lay the track.

[0046] Furthermore, the drive assembly includes a rotary motor 1, a drive sprocket 2, and a tensioning wheel 5. The rotary motor 1 is coaxially arranged with the drive sprocket 2 and is located inside the drive sprocket 2. The rotary motor 1 is used to drive the drive sprocket 2 to rotate in two directions (clockwise rotation and counterclockwise rotation).

[0047] Furthermore, the drive sprocket 2 and tension wheel 5 mesh with the inner track 3, and the drive sprocket 2 and tension wheel 5 are spaced apart. Under the joint support of the drive sprocket 2 and tension wheel 5, the inner track 3 of the closed-loop structure can be fully stretched and tensioned, so that the inner track 3 can form a track with a fixed shape, allowing the outer track 4 to wrap around the inner track 3 with a fixed shape. Thus, the length of track laying can be calculated by the number of turns of the outer track 4 on the outer wall of the inner track 3, which is used to accurately determine the length of track laying.

[0048] It is worth noting that the drive sprocket 2 and the tensioning wheel 5 are arranged parallel to each other in the horizontal direction, so that when the outer track 4 is wrapped and stacked on the inner track 3, the track space in the vertical direction can be evenly distributed to the horizontal direction, saving the track space in the vertical direction and facilitating the overall transportation and storage of the track.

[0049] Specifically, on one hand, when the rotation direction of the rotary motor 1 is opposite to the winding direction of the outer track 4 on the inner track 3, the drive sprocket 2 moves synchronously and in the same direction as the rotary motor 1. The drive sprocket 2 drives the inner track 3, which meshes with it, to move synchronously and in the same direction. The tension wheel 5 is passively driven by the inner track 3 and moves synchronously and in the same direction as the drive sprocket 2, thereby driving the fixed end of the outer track 4, which is fixed on the inner track 3, to move synchronously. Thus, the outer track 4, driven by the fixed end, can be wound section by section onto the inner track 3, causing the track to retract.

[0050] On the other hand, when the rotation direction of the rotary motor 1 is in the same direction as the winding direction of the outer track 4 on the inner track 3, the drive sprocket 2 moves synchronously and in the same direction as the rotary motor 1. The drive sprocket 2 drives the inner track 3, which meshes with it, to move synchronously and in the same direction. The tension wheel 5 is passively driven by the inner track 3 and moves synchronously and in the same direction as the drive sprocket 2, thereby driving the fixed end of the outer track 4, which is fixed on the inner track 3, to move synchronously. Thus, the outer track 4, driven by the fixed end, separates from the inner track 3 section by section from the outside to the inside, causing the track to unfold.

[0051] To enable a fixed connection or relative stillness between the outer track 4 and the inner track 3, a connecting plate 7 is also included, such as... Figure 3 As shown, the fixed end of the outer track 4 is fixedly connected to the inner track 3 by a connecting plate 7.

[0052] Specifically, the connecting plate 7 is disposed on the fixed end of the outer track 4 and the side end face of the inner track 3. The connecting plate 7 is sleeved on the pin of the fixed end of the outer track 4 and the inner track 3, so that there is no relative displacement between the two.

[0053] In one embodiment, the outer track 4, inner track 3, and connecting plate 7 are detachable, allowing the fixed end of the outer track 4 to be fixedly connected to different sections of the inner track 3 as needed, enabling the outer track 4 to be fixed at any position on the inner track 3. Furthermore, this detachability between the outer track 4 and the inner track 3 allows for separation of the outer track 4 and inner track 3 during track maintenance via the connecting plate 7, enabling separate maintenance and increasing efficiency while reducing costs.

[0054] In another embodiment, the fixed end of the outer track 4 is hinged to the inner track 3 via a hinge shaft of the same width as the track, so that the outer track 4 and the inner track 3 are relatively stationary. When the inner track 3 rotates, the outer track 4 can be wound clockwise or counterclockwise (i.e., wound in both directions) on the inner track 3, so that the outer track 4 is not restricted by the rotation direction of the inner track 3, and its application range is wider.

[0055] Furthermore, such as Figures 4-5 As shown, the outer track 4 includes multiple single-link chains 41, which are arranged in parallel and hinged to each other.

[0056] Furthermore, each single-link chain 41 includes a convex circle 44 and a groove 45. The convex circle 44 is disposed on the upper surface of the single-link chain 41, and the groove is disposed on the lower surface of the single-link chain 41. During the winding process of the track, the convex circle 44 at the top of the single-link chain 41 of the outer track layer engages with the groove at the bottom of the single-link chain 41 of the inner track layer. The inner and outer tracks are directly engaged by the engagement between the convex circle 44 and the groove 45, so that the stacked tracks can be interlocked and misalignment is avoided.

[0057] Furthermore, such as Figures 6-7 As shown, each single chain link 41 also includes a transfer component. Each single chain link 41 includes two transfer components, which are symmetrically arranged at both ends of the single chain link 41 for transferring the linear motor 10.

[0058] Furthermore, the transfer assembly includes a connecting pin 42 and a nut 43. Both ends of the single-link chain 41 are provided with through holes, through which the connecting pin 42 passes. At the same time, both ends of the connecting pin 42 are spirally connected to the nut.

[0059] Specifically, the through hole on the single-link chain 41 is clearance-fitted with the connecting pin 42, ensuring that the connecting pin 42 can rotate freely within the through hole of the single-link chain 41. The nut 43 is threadedly fastened to the end of the connecting pin 42, thereby limiting the position of the connecting pin 42 and ensuring that the connecting pin 42 will not slip out of the through hole of the single-link chain 41.

[0060] It is worth noting that the nut 43 in this embodiment is a round nut in order to ensure that the linear motor 10 can roll on the nut 43.

[0061] When the linear motor 10 is transferred by the transfer assembly, the linear motor 10 is placed on the nut 43, and the linear motor 10 is in a rolling connection with the nut 43 to realize the transfer of the linear motor 10.

[0062] It is worth noting that, such as Figure 6 As shown, the inner spacing of the single chain link 41 is M, the spacing of the inner edges of the nut 43 is N, and the width of the linear motor 10 is L. The width L of the linear motor 10 must be between the spacing N of the inner edges of the nut 43 and the spacing M of the inner edges of the single chain link 41, i.e., it must satisfy the following relationship: N < L < M.

[0063] Specifically, N < L < M is to ensure that the bottom of the linear motor 10 can contact the nut 43, allowing the linear motor 10 to rotate through the nut 43. If L is less than N, the linear motor 10 will not contact the nut 43 and will fall directly onto the cable in the middle of the single-link chain 41. The linear motor 10 will not be able to move, and the motor may damage the cable. If L is greater than M, the linear motor 10 will fall onto the edge of the single-link chain 41, and the linear motor 10 will exceed the range of the nut 43, making it impossible for the linear motor 10 to roll on the nut 43. Therefore, the relationship among the three is: N < L < M.

[0064] Specifically, the linear motor 10 rests on the nuts 43 on both sides. When the linear motor 10 moves, the nuts 43 drive the connecting pin 42 to rotate in the through hole of the single chain 41. Under the drive of the external traction mechanism, the horizontal movement of the linear motor 10 is converted into the rotation of the connecting pin 42, thus enabling the rapid transfer and transportation of the linear motor 10.

[0065] The connecting pin 42 transforms the planar movement of the linear motor 10 into the rotation of the connecting pin 42, changing the dragging to rolling, which greatly reduces friction and saves time and effort.

[0066] Furthermore, such as Figure 8 As shown, it also includes a cable 6 and a clamp 7, which is fixedly welded to a single-section chain 41 and used to hold the cable 6 in place.

[0067] When using, pry open clamp 7 and place cable 6 inside clamp 4 to prevent cable 6 from falling off or getting tangled.

[0068] The radius of the arc segment of the inner track 3 is larger than the bending radius of the cable 6 to ensure that the cable will not be damaged after multiple bends.

[0069] Once all linear motors 10 have been moved to their designated positions, the cables 6 laid inside the outer track 4 are connected to the cable connectors on the linear motors 10, thus completing the cable connection. The starting position of the cables 6 on the outer track 4 should be designed based on the completed deployment and docking status of the linear motors 10, the location of the on-site power cabinet, and the principles of proximity and ease of operation.

[0070] The tracked rapid deployment motor track provided by this invention enables simultaneous operation of three systems: linear motor track laying, linear motor rapid transfer, and cable laying. It has a high degree of integration and improves the efficiency of actual use.

[0071] Example 2

[0072] Another specific embodiment of the present invention, such as Figure 9 As shown, a tracked rapid deployment motor track is disclosed, in which the inner track 3 and outer track 4 of the tracked rapid deployment motor track in Embodiment 1 are replaced with only the outer track 4, and the drive assembly is replaced with a rotary motor 1, a drive sprocket 2 and a support frame.

[0073] The rotary motor 1 is coaxially mounted with the drive sprocket 2, and is housed within the drive sprocket 2. The rotary motor 1 drives the drive sprocket 2 to rotate in two directions (clockwise and counterclockwise). The drive sprocket 2 is meshed with the outer track 4. The rotary motor 1, by driving the drive sprocket 2, allows the outer track 4 to be rolled up or unrolled around the drive sprocket 2, thus enabling the motor track to be retracted or laid. The rotary motor 1 is supported and secured by an external support frame with sufficient ground clearance; the height of the support frame is greater than the radius of the track 4 when fully rolled up.

[0074] During implementation, the outer track 4 unfolds, and the outermost layer of the outer track 4 is pulled forward by the external traction mechanism. At the same time, the rotary motor 1 rotates in the same direction as the outer track 4, driving the drive sprocket 2 to rotate. The drive sprocket 2 drives the outer track 4 to rotate synchronously in the same direction. Under the combined action of the external traction mechanism and the drive sprocket 2, the outer track 4 is unfolded.

[0075] When the outer track 4 is rolled up and retracted, the drive motor 7 rotates in the opposite direction to the rolling direction of the outer track 4, which drives the drive sprocket 2 to rotate. The drive sprocket 2 drives the outer track 4 to rotate synchronously in the opposite direction, thus achieving the retraction.

[0076] This embodiment reduces the space occupancy rate in the horizontal direction, and is suitable for use when the height direction is unrestricted but the width direction is restricted.

[0077] Furthermore, the outer track 4 of this design is rolled up or unfolded on the support frame, so the device has high stability, and the traction mechanism can change the track laying route as needed by changing the traction direction of the traction mechanism, which makes the operation highly flexible.

[0078] Compared with existing technologies, the tracked rapid deployment motor track provided by this invention has a high degree of overall integration and can simultaneously solve the problems of linear motor track laying, linear motor transfer, and cable laying. It has wide applicability, suitable for various linear motor transfers and cable laying operations, with no limitation on laying distance. For applications without pre-set tracks, multiple linear motor segments needing to be connected, and where preparation time is limited, it can significantly improve the efficiency of linear motor placement, transfer, and cable connection.

[0079] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
